I had tendonitis in my elbow...well actually on the top part of my arm, just below my elbow. I used a brace type thing that my hubby had been prescribed, and it helped me so much. Then I found a nicer looking one and bought it from Connecting threads. It shows it with the bar on the bottom, but when you put it on the top of your arm, it helps isolate that tendon and support it. Here is the link

I wore this for a week or ten days and it supported the tendon in the top of my forearm feel so much better, and my elbow felt better too.
